Also, it's the township of Edison, NOt the county who has jurisdiction over approving or denying the application.
You can call the township engineering department at (732) 248-7248 but better is to do directly there and ask the questions as well as get any necessary paperwork to will need to file an application.
Here's the link to information on when you need a permit:
Just to clarify, in addition to applying for the building permits at the building department, the owner usually has to get an approval from the zoning board too (to make sure this is NOT being converted to a separate living space. )
I never said the owner does not have to go to/contact the building department. That's where you get the plans approved and the permits issued.
You CANNOT put in a second kitchen without permits in Edison...you will have to have your contractor (or yourself if you are doing it yourself) submit plans and have the plans aporved, then have it inspected for:
framing (if you are changing/adding walls)
plumbing (installation of gas lines/sinks pipes, etc), and
electrical (if you are changing ANY electrical work, adding lights/ outlets etc)
It's not to make money, but to make sure everything is done up to current codes to prevent flooding from improperly installed pipine/drainage, and god forbid, a fire from faulty electric or gas line installation.
It's also to make sure you are not converting a legal single family home into an ILLEGAL 2 family home.
I know this because I am on the Edison zoning board as well as being a Realtor.
You don't want to be in the same dilemma.
Therefore, talk to the proper town authorities to make the addition/alterations legal.
Best of Luck.
